 Precision light pipe is a fine drawing or cold rolling by a high-precision processing of steel materials. Since no sophisticated bright tube outer wall oxide layer, withstand high pressure without leakage, high-precision, high finish, cold deformation, flaring, flattening a bit without cracks, it is mainly used to produce pneumatic or hydraulic components of products such as cylinders or cylinder, which can be seamless tube, welded pipe also. Precise chemical composition of a light tube of carbon C, silicon Si, manganese Mn, S S, P P, chromium Cr.
